The other great benefit of aeration...temperature control! I ran my aerator in the daytime last winter to keep the pond warmer and moderate temperature changes.
Mike, how are your shiners doing? (Golden shiners?) I threw in seven pounds of 3 to 4 inch GS in March. They seemed to be skilled at avoiding predator attacks, loved and ganged up on Optimal Bass pellets, hunted fish fry and such in the pond light, but by mid-May they had all disappeared.
